Hello, I have noticed that depending on the order in which you provide the dimensions for the SODFL package, the layout recommendation differs. If you switch the b1 dimension with b and L1 with L, you get different padstacks. Is it a bug in the software or is there some other reason for such results? I use the latest version of the PCB Footprint Expert. Please see the attached screenshot for the comparison:  |

This anomaly is a result in the differences between the b-b1 and L-L1 tolerances. The effect has been resolved in the latest V26.03 pre-release update, 2-20-26.
